Thermal Reference Sources (TRS) are hermetically sealed infrared calibration devices. They are most often used for real time calibration of infrared temperature sensors. Custom Thermoelectric's TRS devices contain a highly efficient radiating surface and feedback sensor (PRT). The emissive surface can be rapidly driven in both the cooling or heating direction (2 ºC/sec. typical). Incorporating a solid state thermoelectric module that has been ruggedized to withstand 25G in all directions. Wavelengths of 3 - 5 micron and 8 - 12 micron are typical. Standard and custom designs are available upon request.

Emitter sizes from 0.10 to 4.0 inches.

Proprietary high efficiency radiating surfaces with typical emmisivities of ≥.97

Outstanding point to point uniformity within emitter surface (0.5 ºC typical, up to 0.05 ºC)

Pixel to pixel uniformity's of ± 0.1 ºC

Blackbody temperature ranges of -65 to + 150 ºC

Slew rates of 2 ºC/sec. typical, faster rates available.

Patented ruggedization method to withstand high G requirements.

Window materials available with high transmittance and low reflectance coatings.
